Themes

Guests walked up a golden carpet and through giant "O" and "Z" letters to enter the event.

The Wicked Witch of the West's Winkie guards flanked the entrance.

Traditional interpretations of Dorothy, the Tin Man, the Scarecrow, and the Cowardly Lion were relegated to the entrance; high-fashion versions of the characters were upstairs.

High-fashion versions of the Wicked Witch of the West and Glinda the Good Witch met on a stage in the haunted forest.

Each year the ball has an elaborate ice sculpture. This year it depicted trees in the haunted forest and presided over a raw bar.

Dorothy's crashed farmhouse served as a surround for the bar, and other design elements included a rotating windmill. Black-and-white decor included floral-printed linens that evoked the film's famous poppies.

Guests entered the main ballroom for dinner through an arched tunnel with 180-degree projection mapping and sound to evoke a tornado.

Instead of an Emerald City, designers opted for a "Crystal City." The linens had embroidered sequins that caught the light.

Headliner Diana Ross performed a 40-minute set.

The centerpiece of the after-party was a 30-look runway show from Neiman Marcus Bal Harbour. The after-party theme was "disco butterfly," and the clothing shown had a 1970s "glamazon" look, according to co-producer Clif Loftin.

When Delvinia celebrated its 15th anniversary last August, the Toronto-based digital strategy and customer experience design firm looked to recreate 1950s Havana with cigar rollers, freely flowing rum, models in retro swimwear, and beach balls. The event at the Loft at Andrew Richard Designs even had an indoor pool—or rather, the illusion of one created by a 8- by 18-foot 3-D decal.
